Data sheet

|
|
| By means of a resistor heat is generated by the supply voltage applied after breaking the contact.
This heat prevents any decrease in temperature below the value necessary for the cut-in temperature
TE. In this was, the switch will keep its contact open, irrespective of its ambient temperature.
Cut-in of the switch, and thus closing the circuit, will be possible only after disconnection from
the supply voltage. |

|
|
| Thermo switches only react when external thermal heating affects them. The thermal coupling to the
source of heat is effected by means of a bimetal disk lying directly below the metallic covering
cap. |
|
|
|
| Due to small size, high reliability, independence of location and the fact that it is totally
maintenance-free, a thermo switch is the ideal instrument for perfect thermal protection. |
|
| Types of Contacts/Contact Types |
- KO - break contact which will automatically return into its original position.
- KS - make contact which will automatically return into its original position.
- KB - limiter with mechanical latch/self-holding
- SB - break contact with electric latch/self-holding
